SPECIFICATION forming part of Letters Patent No. 789,362, dated. May 9, 1905.

Application fileu October 25, 1904. Serial No. 229,900.

To (1/7] wit/mt if; Ina/y con/corn:

Be it known that I, EDWARD K. Ems, a citizen of the United States, residing at Emigsville, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Dumping-Wagons, of which the following is a specification.

My present invention relates to improvements in dumping'-\vagons; and the main object of my invention is the provision of a wagon of this character provided with doors forming the bottom of the body thereof and so supported as to form a rigid bottom when closed and to hang loosely when open, capable of an outward, inward, and longitudinal vibration. To attain these objects, I so mount the bottom to the body of the wagon that when open a means is provided whereby the sections are swung clear of the sides and so supported that the sections can swing in all directions without being injured and lifting means being so connected to the sections as to be clear of the contents and readily accessible to the driver.

In the accompanying drawings, Figure l is a side elevation of the complete wagon with the sections or doors. of the bottom closed. Fig. 2 is a bottom plan view thereof. Fig. 3 is a rear end view thereof with the doors open. Fig. f is an enlarged detail view of the upper portion of one section and. the body of the wagon, showing the support therefor and the connection for the lifting means. Fig. 5 is a cross-section through one of the supporting means and the vehicle-body and section.

In wagons of this character heretofore manufactured the doors or sections have been either rigidly hinged to the vehicle-body or supported by means of a flexible connection, such as chains; but with either or both of these supports the guides for preventing the outward movement of the upper edges of the sections have been liable to injury when the sections strike an obstacle, and it is therefore my object in designing a dumping-wagon to so mount these sections that they are guided out of the way of the lower edges of the body and at the same time be so supported and guided as to yield when struck by an obstacle,

and thus prevent the breakage of any part. By means of my improved guiding means not only will the sections have their upper edges clear of the wagon-body, but will cause the lower edges to incline inward, so that the sections or doors are more easily closed with less liability of jamming should some of the contents cling thereto.

My dumping-wagon consists primarily of the body 1, having inclined forward and rear ends 2 and 3, respectively. The sides l extend the full length of the body and are provided with the usual reduced projecting portions 5, which assist, with the ends, in forming the hopper of the wagon.

Secured upon each side of the wagon-body, upon each side of the hopper thereof, are two straps 6, provided with the eyes 7 for the reception of a pin or bolt 8, by which the curved arms or yielding guides 8 are supported. Secured to the arms, near the upper ends thereof, are the bails 9, which carry the chains 10, said chains having their lower ends connected to the upper edges of the sections or doors 11. In order to accol'nmodate the bails 9 when the sections or doors are closed, I provide recesses or slots 12 in the sides of the body. These arms or guides 8 have the bails 9 so attached that when the doors are swung open the upper edge of the doors move outward beyond the lower edges 13 of the sides of the body, and should the doors strike an obstacle the arms can be moved farther outward as the doors are moved either upward or outward, thus yielding to the movement of the doors and readily assuming their normal position when the obstacle is passed.

In order to control the opening and closing of the doors, the short curved end lt of the arms 8 have connected to the inner faces thereof the pull-chains 15, which pass through the metal-incased openings 16, near the inner edges of the doors at their forward and rear ends, over the pulleys 17, mounted upon the front and rearends of the body. The chains passing over the rear pulleys have their upper ends connected to the rear ends of the pull-rods 18 after passing through an opening .19 and over a pulley 20, said pull-rod being connected, by means of the chains 21, to the ends of the rotatable or winding shaft 22, journaled in the forward part of the sides of the body, while the forward chains pass through the forward portion of the body and are connected to the shaft 22 within the body, as shown in Figs. 1 and 5. By this means when the lever 23 is operated upon to revolve the shaft the liftingchains are all simultaneously pulled upon,and the doors or sections are moved into a closed position. By means of the ratchet-wheel 24 and the dog or pawl 25 this shaft is always under control, and when it is desired to dump the body all that is necessary is to release the pawl and ratchet, and the weight of the contents will force the doors apart and dump the body. When the doors are closed, the curved ends of the guides project slightly under the same and with the chains form a support whereby the doors are rigidly held closed. Guidechains 26, being connected to the lifting-chains and door, prevent too much side strain being exerted upon the lower ends of the arms 8. It will also be noticed that the doors or sections are provided with the projections 27 at each end, whereby the lifting-chains are at all times clear of the contents of the wagon, so that the contents do not in any way interfere with the operation.

From the foregoing description, taken in connection with the drawings, it is evident that I provide a dumping-wagon embodying features of merit over the wagons in general use and one whereby the sections or doors are easily closed and held in such position, quickly and easily released to dump the wagon, and at the same time swing clear of the contents, the said doors being so mounted as to be capable of moving in every and all directions without injury to any of the mechanism, as they are flexibly swung and carried by yielding guiding means.

The main feature of my invention is the idea of supporting the doors or sections upon a pair of hinges the upper ends of which are secured to the side of the wagon-bod y, while to the lower yielding ends Isecure the doors and connect the lifting mechanism, thus allowing the doors to swing loosely and be capable of movement in every direction.

I/Vhat I claim as new, and desire to secure by Letters Patent, is

1. In a dumping-wagon, the combination with a body and the side-boards thereof, of doors forming the bottom of the body, guiding means for the doors secured upon the exterior of the side-boards, and flexible supporting means connected to the doors and guiding means for the purpose set forth.

2.
